I'm confused about the fitness features of smartwatches, like heart rate monitoring, calorie burn data, or sleep analysis. How accurate do you think these tools are? Can they really measure our steps, sleep depth, or stress levels in our bodies, or is it just an estimate? Can you share your experiences or general opinions on this without comparing different brands?
How reliable are smartwatches for fitness tracking?

Reliability-wise, if I compare smartwatches to standard fitness trackers like GPS pendants, smartwatches show the general trend but can lag a bit in accuracy. For instance, step counts might have a 5-10% deviation, or sleep analysis tends to rely more on movement rather than actual rest.
Yo man, my Fitbit’s pretty spot-on for steps and sleep tracking, but it’s always overestimating calories. And the Apple Watch? Heart rate’s solid, but the stress level thing feels off—it’s just looking at my heartbeat.
